Electric shedding device in weaving machine

Abstract

A shedding device in a weaving machine including one or more motor groups with a plurality of motors corresponding to a plurality of heald frames which are supported by a plurality of supporting mechanisms arranged in the forward and backward direction of the weaving machine. The motors of each motor group are arranged in the upward and downward, rightward and leftward directions. Two or more motors operating as at least part of the motor group form one or more motor rows. Each motor is connected to the supporting mechanism of a heald frame through a connecting member. Adjacent motors in the motor row or rows are related to non-adjacent heald frames among the heald frames corresponding to the support mechanisms.

What is claimed is:  
     
       1. A shedding device in a weaving machine, comprising: a support mechanism group including a plurality of support mechanisms individually supporting a plurality of heald frames so as to move said plurality of heald frames upward and downward, a motor group including a plurality of motors corresponding to said plurality of heald frames with their output shafts directed in the forward and backward direction of the weaving machine, and a motion converting mechanism group including a plurality of converting mechanisms each having a long connecting member for connecting the plurality of motors with the corresponding plurality of support mechanisms, 
       wherein said plurality of motors in said motor group are disposed in the upward and downward, rightward and leftward directions, wherein two or more motors in said motor group form one or more motor rows arranged in the longitudinal direction of said connecting member, and wherein adjacent motors within said motor rows correspond to non-adjacent heald frames.  
     
     
       2. A shedding device as defined in  claim 1 , further comprising: a second support mechanism group including a plurality of second support mechanisms for individually supporting additional heald frames so as to move upward and downward; a second motor group including a plurality of second motors corresponding to said additional heald frames and with their output shafts directed forward and backward of the weaving machine; and a second motion converting mechanism group including a plurality of second converting mechanisms each with a long second connecting member for connecting said plurality of second motors with the corresponding plurality of second support mechanisms, 
       wherein the second motors of said second motor group are arranged in the upward, downward, rightward and leftward directions, wherein two or more motors in said second motor group form one or more second motor rows arranged in the longitudinal direction of said second connecting member, and wherein adjacent motors within said second motor row are related to non-adjacent heald frames among the additional heald frames supported by said second support mechanisms.  
     
     
       3. A shedding device as defined in  claim 2 , wherein said second motor group and the motor group described in  claim 1  are arranged in different positions in at least one direction selected from the forward and backward direction, the upward and downward direction and the rightward and leftward direction. 
     
     
       4. A shedding device as defined in  claim 1 , wherein the motors of the same motor row are related to the heald frames corresponding to the motors of said motor row such that the motors nearer to the end portion of the connecting member on the side opposite to the motors are related to the heald frames on one of the forward side and the backward side nearer to the side where the motor group is arranged, among the heald frames corresponding to said support mechanisms. 
     
     
       5. A shedding device as defined in  claim 4 , wherein heald frames adjacent to the heald frames related to the motors in the same row are related to other motors in said motor group not belonging to the same row. 
     
     
       6. A shedding device as defined in  claim 1 , wherein the motors of said motor group are arranged in plural rows respectively in the widthwise direction and upward and downward direction of the weaving machine; 
       wherein the heald frames supported by the support mechanisms of said support mechanism group are divided into a plurality of groups adjacent to each other, each of which includes a number of heald frames corresponding to the number of rows of motors arranged in the upward and downward direction,  
       wherein the motors of the first upper and lower rows nearest to the end portion of said connecting member opposite said motors are made to correspond to the heald frames of a first heald frame group nearest to the forward side or the backward side of the weaving machine, and  
       wherein the motors of the other upper and lower rows and the heald frames of the other groups are made to correspond such that the order of proximity of the upper and lower rows to which the motors belong relative to said first upper and lower rows coincide with the order of proximity of the group to which said heald frames belong relative to said first heald frame group.
